Setting: Eugene, Oregon.
Richard Kimble, who normally avoids having his picture taken, allows himself to be photographed with the child in this story due to the child's great fondness for him.
The address on Pryor's car registration is 617 Kronman Lane, Eugene Oregon. Harry Kronman was a frequent writer on The Fugitive (1963).
The music cue heard underneath the scene where Harold Cheyney first appears outside the hospital and again when he breaks the window in the hideout was from Two (1961), composed by Van Cleave and reused by the CBS Radio Mystery Theater (1974-1982) as its theme.
The show mentions that the ransom drop is along highway 126. While the episode supposedly takes place in Oregon, there is also a highway 126 in northern Los Angeles County, running west into Ventura County. It runs along the Santa Clara river, which is mostly dry outside of the rainy season. It is along this highway, only two lanes in 1964, where the ransom drop was likely filmed.
